Local hosted images are displayed in Safari but not with Chrome

I solved the problem to display images stored locally with a local web server and an image url.
(The problem is described here as well: Links to local files)

That works with Safari (left in the screenshot below) but not with Chrome (right). I assume there is a security issue within Chrome but I wasn’t able to find out what could cause the different behaviour.

If I call the image url directly in Chrome (e.g. http://offer.media.kuma:8888/EBAY/EBAY-143876293069.jpg), the image is displayed.

Has anyone an idea how to find the right settings for Chrome?
Thank you.
